Table 3.
Predicted Mean Time-to-Defibrillation and Mean Survival Probability results of simulations of 4 systems (A: mobile responders providing CPR only; B: mobile responders provisioned with AEDs; C: drone AED delivery with bystander application; D: drone AED delivery with mobile responder application).
| System | Mobile Responder Density (per sq. km) | Drones | Mean Time to Defib (decimal minutes) | Mean Time to CPR (decimal minutes) | Mean Survival Probability |
|---|---|---|---|---|---|
| A | 2 | N/A | 6.8* | 5.4 | 0.22 |
| A | 5 | N/A | 6.8* | 4.8 | 0.24 |
| A | 8 | N/A | 6.8* | 4.5 | 0.24 |
| B | 2 | N/A | 5.4 | 5.4 | 0.26 |
| B | 5 | N/A | 4.8 | 4.8 | 0.29 |
| B | 8 | N/A | 4.5 | 4.5 | 0.30 |
| C | N/A | 1 | 5.6 | 5.6 | 0.27 |
| C | N/A | 2 | 5.2 | 5.2 | 0.28 |
| C | N/A | 5 | 4.7 | 4.7 | 0.30 |
| D | 2 | 1 | 6.7 | 6.7 | 0.22 |
| D | 2 | 2 | 6.7 | 6.7 | 0.22 |
| D | 2 | 5 | 6.6 | 6.6 | 0.23 |
| D | 5 | 1 | 6.0 | 6.0 | 0.26 |
| D | 5 | 2 | 5.8 | 5.8 | 0.26 |
| D | 5 | 5 | 5.6 | 5.6 | 0.27 |
| D | 8 | 1 | 5.8 | 5.8 | 0.26 |
| D | 8 | 2 | 5.5 | 5.5 | 0.27 |
| D | 8 | 5 | 5.3 | 5.3 | 0.28 |
| EMS | N/A | N/A | 6.8 | 6.8 | 0.20 |
*System A does not provide defibrillation, thus time to defibrillation is equivalent to the simulated EMS time.
